3T's Straight Aero Extensions are made of durable, stiff aluminum and feature no bends for an ultra low position during your time against the clock.
- Standard 22.2-mm diameter
- 305mm maximum extension from center line of bar clamp

For 56 years, 3T products have offered a combination of Italian elegance and performance. The Apto once again combines both with a beautiful shape and a lightweight, stiff and strong structure. The reversed bolts clean up the faceplate, while their wide spacing increases the connection to the handlebars. Its double steerer bolts securely hold the stem in place.

3T's Arx II is a subtle refresh of the well-liked Arx alloy stem, which has found a place on every sort of bicycle since its launch in 2007. The faceplate is drawn in tighter at top and bottom for a more ovalized frontal appearance, while retaining the cutout 3T logo. The sides of the extension are slightly flattened for a more sculpted look by comparison with the tubular section of the first-generation Arx. A single M7 bolt clamps the stem to the fork steerer, instead of the twin M5 bolts previously used, and the Allen bolts used on the original Arx have been replaced by no-strip Torx bolts.
- Stack height: 40mm
- Weight: 135g (110mm)

Ionic is a seatpost design featuring the sophisticated and robust, 3T–exclusive DiffLock seat clamp. Ionic–0 places the seat clamp assembly in line with the seatpost for zero setback. Many athletes seeking outright speed favor this more forward position on the bike. Some frame designers are also specifying a slacker seat tube so riders can set their bike up with an inline post, which is lighter than a setback post. The splined alloy DiffLock coupling is a highly accurate method of setting saddle angle, needing only lightweight clamping by side-mounted bolts. It is especially useful for fine adjustment of saddle setback, which can be done without impacting saddle angle. The Ionic–0 Pro is fabricated in aluminum alloy with a shot-peened, black-anodized finish.
- Aluminum shaft with alloy Difflock seat clamp fits only saddles with 7mm round-section rails
- Clamp Style: Standard Rails
- Color: Black
- Weight: 230 grams

Zero25 is a lightweight, universal seatpost with a twist: it’s two seatposts in one. The two clever, reversible saddle rail clamps transform the post from zero saddle setback to 25mm setback. All that’s needed is to flip the clamps from one side of the seatpost head to the other and the offset changes.
No more problems with getting the wrong seatpost or needing another one when you change the type of saddle you use – it now takes 30 seconds to transform your seatpost. And the best news is that despite the double functionality, the Zero25 is even lighter than our previous seatpost.
Zero25 Pro has an alloy pillar and comes in two diameters, 27.2mm and 31.6mm, and one length, 350mm.

3T's Stylus is a fresh take on the 2-bolt aluminum seatpost. The transition from the pillar to the saddle clamp assembly is a finned, rearward swoosh suggestive in shape of the classic one-bolt posts of yore. But the clamp bolts are deployed to either side of the saddle-support cradle, conferring greater stability and easier adjustment. The Stylus 25 places the seat clamp assembly with 25mm of setback for a rearward position on the bike.

3T's Ionic aluminum seatpost is stiff, durable, and features their Driftlock seat clamp assembly for 25mm of setback. This gives you the option of a more rearward position on today’s shorter framesets.

Zero25 can handle any type of seatpost rails, from round to all oval shaped carbon rails.

3T's Ergoterra is wide, ergonomic and designed specifically for cyclocross. This carbon bar's flared drops angle outwards by six degrees for comfort and control over rough terrain. A reinforced central section on the top adds stiffness as well as strength for the option of mounting cross top bar brakes. It has a compact drop and reach, perfect for sprints and reaching your brakes at all times.
- Viewed from above, the drops angle outwards by 6°
- 45cm model is 42cm at the hoods, while the 47cm model is 44cm at the hoods
- Compound-curved bends preserve the vertical alignment of brake/shifter levers at their mounting point, so outward flare does not alter shifters’ ergonomics
- The 31.8 mm center section is extended and reinforced to mount cyclocross top brake levers
- On rough ground that jostles the rider’s handhold, Ergoterra offers more lateral clearance for the forearms, helpful for run-ups

Arx, Latin for stronghold and bridge, is 3T’s race-proven design for the perfect connection between fork and handlebar and suited to all cycling disciplines. Clamp design is optimized to ensure a secure fit on composite steerers and bars without the need for potentially damaging high torque values during assembly. 3T inhouse tests show Arx’s clamp by far exceeds the CEN standard, and also that it works very well with other brands of handlebar. Arx Ltd is the carbon-fiber version of the stem, with Ti bolts. Super-light and super-stiff, it is a highly evolved, modern design weighing just 118g.

3T's Integra LTD stem is the perfect solution for any Garmin Edge owner. A Garmin-specific mount is built into this stiff, streamlined stem to keep your cockpit tidy and aero. The Integra's carbon construction keeps it rigid and light for sprints and climbs alike. If you're not riding with your Garmin, or if you don't even own one, the Integra can be fitted with its front end plate for an even more aerodynamic look.

Since its introduction, the most common feedback on our Ergonova drop bar was “don’t change a thing”. But observing how our customers ride, we noticed many spend considerable time holding the bars in the corner section, especially while climbing. Designing the corners specifically for this function has created a bar that is supremely comfortable not only on the tops and the drops, but also in this intermediate position. Further redesigns to the hood and drop shapes to accommodate the latest shift/brake levers help to create the new standard in ergonomics
- Material: Unidirectional carbon
- Cable routing: Internal cable channels
- Stem torque: 5Nm maximum
- Shift/brake lever torque: 8Nm maximum
- Clip-ons: Not compatible
- Di2 compatibility: Fully compatible, including with Di2 bar plug Junction A

3T's Luteus Team is an all-carbon cyclocross fork designed for use with disc brakes. It features include a tapered steerer and aluminum-faced fork ends for precise handling and simple wheel changes. It supports brake calipers for use with standard 160mm brake rotors. The left fork blade is reinforced at the brake mounting pillars to compensate for the stresses imparted by disc braking. On its outer face, there is a recessed channel with two integrated fixing points for tidy brake cable/hose management. Plus, the fork ends face forwards and have aluminum inserts to better resist the lateral stresses transmitted through the hub by rough terrain.
